[R] make check fails tools-Ex in 2.5.0

[Pacey, Mike]

Hi folks,

I'm attempting to compile and install 2.5.0, and "make check" is failing
one of the earlier sanity tests. I'll append the relevant portion of the
Rout.fail file below, but I've narrowed it down manually to a single
command:

> sessionInfo()
R version 2.5.0 (2007-04-23) 
x86_64-unknown-linux-gnu 

locale:
LC_CTYPE=en_US.iso88591;LC_NUMERIC=C;LC_TIME=en_US.iso88591;LC_COLLATE=e
n_US.iso88591;LC_MONETARY=en_US.iso88591;LC_MESSAGES=en_US.iso88591;LC_P
APER=en_US.iso88591;LC_NAME=C;LC_ADDRESS=C;LC_TELEPHONE=C;LC_MEASUREMENT
=en_US.iso88591;LC_IDENTIFICATION=C

attached base packages:
[1] "stats"     "graphics"  "grDevices" "utils"     "datasets"
"methods"  
[7] "base"     
> library('tools')
> db <- Rd_db("base")
> db
list()

Earlier versions I've compiled and installed (2.3.1, 2.4.0) populate db
with a lot of information. Any suggestions on what might be wrong here?

Regards,
Mike.
